Covworm iav flange npauj npaim valve(tseem hu ua worm iav flange nrov plig plawg valve) yog ib qho yooj yim regulating valve, feem ntau yog siv rau on/off tswj thiab ntws tswj ntawm qis - siab pipeline media. Nws yog qhov tsim nyog rau kev xa cov corrosive lossis tsis yog -cov kua dej corrosive hauv engineering systems xws li thee gas, natural gas, chemical smelting, power generation, and environmental protection.

Worm Iav Flanged Npauj Npaim Valve Cov yam ntxwv
Hnav Gear Tsav Mechanism:
Cov cab iav reducer tsav lub qia kom tig, ua kom lub phaj npauj npaim tig 0℃~ 90℃qhib thiab kaw. Nws muaj qhov sib kis loj (feem ntau yog 15: 1 txog 60: 1), tsis tshua muaj kev ua haujlwm torque, thiab yooj yim rau kev khiav lag luam, ua rau nws tshwj xeeb tshaj yog haum rau kev tuav tswj ntawm loj - txoj kab uas hla li qub. Cov cab iav tsav muaj tus kheej -locking muaj nuj nqi; Thaum lub log tsheb nres, tus npauj npaim phaj txoj haujlwm tseem nyob ruaj khov, tiv thaiv qhov nruab nrab siab los ntawm kev ua kom nws tig ntawm nws tus kheej thiab ua kom muaj kev nyab xeeb.
Flanged Connection Design:
Lub valve muaj flanges ntawm ob qho kawg, uas ncaj qha bolted rau cov yeeb nkab flanges. Qhov no tso cai rau kev yooj yim installation, zoo sealing, thiab yog haum rau siab -siab, loj - txoj kab uas hla pipelines. Piv rau wafer- hom npauj npaim li qub, flanged kev sib txuas yog qhov muaj zog dua, thiab kev saib xyuas tsis tas yuav tshem tawm tag nrho cov kav dej.
Npauj Npaim Phaj Structure:
Lub disc- zoo li tus npauj npaim phaj yog siv los ua qhov qhib thiab kaw. Kev tsim kho kom yooj yim txo cov dej tsis kam thiab kev siv zog. Raws li txoj kev sealing, cov ntsaws ruaj ruaj tuaj yeem raug cais raws li hauv qab no:
Soft Seal: Lub nplhaib sealing siv cov ntaub ntawv elastic xws li roj hmab nitrile thiab fluororubber, embedded nyob ib ncig ntawm lub valve lub cev los yog npauj npaim phaj. Nws muaj kev sib khi zoo heev (txog li xoom xoom), tab sis tsis muaj qhov kub thiab txias (nitrile roj hmab: -40℃-90 degree; fluororubber: -20℃-200 degree).
Hlau Foob: Lub nplhaib sealing siv cov khoom siv hlau xws li stainless hlau thiab cobalt-raws li alloys. Nws yog cua sov- tiv taus (txog 815 degree), hnav- tiv taus, thiab muaj lub neej ua haujlwm ntev, tab sis nws cov sealing kev ua tau zoo me ntsis qis dua cov ntsaws ruaj ruaj.
Eccentric Design
Ib qho Eccentric Structure: Lub valve qia centerline yog offset los ntawm npauj npaim phaj chaw, txo qhov qhib thiab kaw kev sib txhuam thiab txuas lub nplhaib sealing lub neej.
Ob chav Eccentric Structure: Ib qho angular eccentricity yog ntxiv rau cov qauv eccentric nkaus xwb, tsim kom muaj cov nyhuv cam kom ua tiav qhov "tighter li nws kaw" sealing muaj nuj nqi.
Triple Eccentric Structure: Siv cov nyhuv cam kom tshem tawm tag nrho kev sib txhuam ntawm lub rooj zaum valve thiab lub nplhaib sib khi thaum lub sijhawm 90-degree stroke. Haum rau siab - qhov kub thiab txias, nws muaj kev sib khi zoo heev.
